In the liquid-fuel sense, “paraffin” is a common British term corresponding to American “kerosene.”
Fast Test
If you mean the clear petroleum fuel for heaters or lamps, choose the regional term expected by your audience; if you mean wax, use “paraffin” or “paraffin wax,” not “kerosene.”

Treat the pair as regional equivalents only in the liquid-fuel sense. “Paraffin” also names paraffin wax, which “kerosene” does not.
